absorbing devices for useionl railway cars,

and it is the object thereof to provide a buffer for this purpose having; a non-metallic yielding facing for receiving the shock and reducin the noise ofthe first impact upon the bu er, springs arranged to receive and to yield more or less under the pressure exerted upon the buffer subsequent to the first impact, and means enabling a certain tilting movement of the buffer-head so that its face may engage squarely `with a contacting body whose face is not parallel to the end of the car on which the buffer is disposed.

A construction embodying my invention is shown in the accompanying drawings, in which- Figure 1 is a side view of theibulfer and a part of the dead-wood of a car on which it is placed, Fig. 2 is a front view ofthe same, Fig. 3 is a longitudinal vertical sectional view thereof, and Fig. 4 is a transverse vertical sectional View onthe plane of the line -m of Fig. 3.

There is shown in the drawing a part of the end-framing or dead-wood 1 of a railwa car. Crdinarily two of the buffers would be placed on each end of the car, being disposed near the ends of the deadwood. In the structure shown a rectangular plate 2 is set into the face `of the deadwood and secured thereto` by lag-screws 3 which pass through the corner portions of the plate. The circular `bulfer-plate 4 is connected with the dead-wood plate 2 by bolts 5 which pass slidably through the latter and extend into recesses 6 formed in the dead-wood behind the plate. The plates 2 and 4 are held in a s aced relation to each other by the springs and 8. The heavy spring 7 is arranged centrally tothe plates, the smaller springs 8 are disposed one around each of the bolts 5, and the ends of each of the springs fit into shallow recesses formed in the adjacent faces of the plates. The bolts 5 normally hold all of the springs under a certain compression. On

the front face of the plate 4 a circular block` or plinth 1l of non-metallic resilient cushioning material, such as rubber, is secured by screws12 of which the heads are set` down into suitable recesses provided therefor in the face of the plinth. On the inner face of the plinth, adjoining the face of the plate 4 are recesses for the heads of the bolts 5.

The operation of the buffer will be apparent from its structure. The first shock or impact of a body striking the buffer will be received by the rubber cushion 1l, which will render the blow ractically noiseless. If the pressure exertedpis greater than the normal or initial compression of the springs 7 and 8, the same will then yield, the inner ends of the bolts 5 passing down into the recesses Gin the deadewood. Should the face of the body engaging the buffer not be parallel thereto, the buffer-head `may tilt more or less, as required, the springs 8 at one side being compressed more than the others. It will be observed that as the lag-` screws 3 are placed at the corners of the plate 2 which extend beyond the periphery of the plate 4, said screws may be inserted or removed and the entire device placed uponor `removed from the deadwood `Without disassembling the parts.

Now, p having described my invention, what I claim and desire to secure by Letters Patent is:

1. In a car buffer, the combination with a recessed dead-wood, of a plate fixedly secured thereto, bolts passing slidably through the plate into the recesses in the dead-wood, a second plate connected with the outer ends of said bolts, springs disposed around the bolts between the plates, a spring disposed between the plates and held centrally thereto, and a rubber facing disposed on the side of the outer plate op` posite the springs.

2. In a car buffer, a recessed dead-wood, a plate secured thereto, a buffer-plate, bolts connected therewith and extending slidably through the dead-wood plate into the `re-` cesses in the dead-wood, and springs disposed between the plates and normally held under compression by the bolts, one of the springs being relatively strong and disposed centrally to the plates, and the other springs being weaker than and arranged symmetrically about the 'central spring.

3. In a car buffer, a fixed plate, a movablt` plate normally disposed parallel to theV fixed plate, a heavy spring disposed between Vthe plates centrally thereto, lighter springs disposed between the peripheral portions of the plates, means slidably connected with one of the plates for limiting'the separation of the plates and holding the springs normally under a certain compression, and a block of resilient material secured on the face of the movable plate. to receive the rst i 3 impact of bodies thereon..

lnv testimony whereof I have hereuntosubscribed my name in the presence of two witnesses.
